Assessing earthquake effects on archaeological sites using photogrammetry and 3D model analysis
No full textThis paper evaluates the application of photogrammetric recording to seismically-affected archaeological sites from the moment of on-site data acquisition through to the analysis of the resulting 3D model. This methodology facilitates (i) rapid but accurate recording of seismically-damaged archaeological contexts, (ii) three-dimensional reconstructions, (iii) the documentation of archeological features (e.g. plans, sections, elevations), and (iv) the extraction of additional information and data for archaeoseismological analysis (DEMs, for instance). Not only is greater detail observed using these methods but it can also be quantified at a distance from the target site, thereby extending the researcher's time in the field. 3D photogrammetry and modelling also reduce the risk that small but significant features such as seismic fractures and deformations are overlooked. This paper draws on evidence from two case studies of the EU-funded ArMedEa project (Archaeology of Medieval Earthquakes in Europe, 1000-1550 AD), namely the Islamic fortified village of El Castillejo (Guajar Faragüit, Granada, Spain) and the crusader castle of Saranda Kolones (Paphos, Cyprus)
A generic toolkit for the visualization of archaeological features on airborne LiDAR elevation data
No full textA range of techniques have become established for the visualization and analysis of airborne LiDAR elevation data within the field of archaeology. In this paper we discuss the visualization of test data representing archaeological features in a variety of terrains using a suite of techniques, all available through generic geographical information system or image processing software. These comprise elevation shading using constrained colour ramps, slope analysis, hill-shading, principal component analysis of multi-azimuth hill-shading, local relief models and solar insolation modelling. The strengths and weaknesses of each technique are discussed and a generic toolkit, suited to the visualization of airborne LiDAR data for archaeological purposes, is presented. © 2011 John Wiley & Sons, Ltd
Predicting the Effects of Parameters Changes in Stochastic Models through Parallel Synthetic Experiments and Multivariate Analysis
No full textUsually researchers require many experiments to verify how biological systems respond to stimuli. However, the high cost of reagents and facilities as well as the time required to carry out experiments are sometimes the main cause of failure. In this regards, Information Technology offers a valuable help: modeling and simulation are mathematical tools to execute virtual experiments on computing devices. Through synthetic experimentation, researchers can sample the parameters space of a biological system and obtain hundreds of potential results, ready to be reused to design and conduct more targeted wet-lab experiments. A non negligible achievement of this is the enormous saving of resources and time. In this paper, we present a plug-in-based software prototype that combines high performance computing and statistics. Our framework relies on parallel computing to run large numbers of synthetic experiments. Multivariate analysis is then used to interpret and validate results. The software is tested on two well-known oscillatory models: Predator-Prey (Lotka-Volterra) and Repressilator
La Freiheitsschrift e gli inizi di una nuova filosofia della persona
No full textNella Freiheitsschrift di Schelling la nuova definizione di libertà come "facoltà del bene e del male" non è più comprensibile all’interno della tradizionale visione della libertà come scelta ma implica un decisivo spostamento di prospettive da una filosofia della coscienza a una filosofia della persona: la libertà si esercita non nella decisione, ma nella formazione (Bildung) della persona
Combining Probabilistic Dependency Models and Particle Swarm Optimization for Parameter Inference in Stochastic Biological Systems
No full textIn this work we present an efficient method to tackle the problem of parameter inference for stochastic biological models. We develop a variant of the Particle Swarm Optimization algorithm by including Probabilistic Dependency statistical models to detect the parameter dependencies. This results in a more efficient parameter inference of the biological model.We test the Probabilistic Dependency- PSO on a well-known benchmark problem: the thermal isomerization of α-pinene © 2012 Springer-Verlag GmbH
DEVELOPMENT OF A EXPERIMENTALLY VALIDATED MODEL FOR SOLID STATE HYDROGEN STORAGE DESIGN OF MATERIAL AND TANK
No full textEDen is a European project, supported by FP7 – JTI
FCH. It aims to develop an innovative embedded system for the
storage of energy, thank to combination and thermal integration
between a SOFC (capable to work like SOE) and a innovative
solid state hydrogen storage tank. In the proposed work, the
objective is the optimization through modeling of behavior and
physical performance for hydrogen storage solution in solid-state
material (Mg-based metal hydrides). The candidate material for
hydrogen storage, and final pellet (utilized inside tank) have been
defined through the identification of best physics, to better
describe gas’ diffusion phenomena and thermal exchange inside
the storage tank
